Kordyana brasiliensis for the biological control of Tradescantia fluminensis

We are conducting a risk analysis for the proposed release of the fungus Kordyana brasiliensis into Australia. The purpose of this release is to control the weed ‘Wandering Trad’ (Tradescantia fluminensis).

The use of exotic biological control agents to control invertebrate pests, weeds and other organisms has been common in Australia for many years. Releasing pathogenic, herbivorous, predatory or parasitic organisms into the Australian environment can have potential “off-target” risks. This means risk to other plants or invertebrate animals not targeted by the biological control agent.

We began this risk analysis in response to an application to release Kordyana brasiliensis to control Wandering Trad. The application was submitted by the Commonwealth Scientific and Industrial Research Organisation (CSIRO).

We have now released a draft report, which:

  • estimates off-target risks and potential consequences of the release
  • evaluates the risk to be Negligible, which meets Australia’s appropriate level of protection (ALOP)
  • proposes the release of the biological control agent Kordyana brasiliensis.

You can now provide comments on the draft report. In particular, on the proposal to release Kordyana brasiliensis.

We will consider all comments. This includes comments on the application from CSIRO and the risks we have identified in the draft report.

To make a submission:

  • read the draft report
  • submit your feedback via our online form, or by post or email.

We will consider all comments before preparing the final report.

Submit your feedback by 12 November 2018.
